The Automatic Bike Safety System is a bike accessory that enhances the safety of the rider through the use of brake lights, turn signals, and headlights. The system employs an Arduino Nano to control the behavior of the lights, a gyro meter, a reed switch, and two relays. The gyro meter records data relevant to the bike handlebar's position and sends that information to the Nano in order to control the turn signal, the relays are used to create the blinking effect of the turn signal, and the reed switch is a magnetic sensor that detects whenever the bike's brake is activated, sending a signal to the Nano to control the brake lights. Notably, the brake lights will activate due to the tension of the front brakes. The main challenges of this project mostly involved coding the Nano to control the lights in the desired fashion. If given more time or a second opportunity to work on the project, we would strive to also implement an audio feature for the system that would create a clicking sound whenever the turn signals were active, similar in behavior to the turn signal of a car.
